APPARATUS PRODUCING CURLED FLAKED SOAP.

Application filed February 5, 1923. $erial No. 616,899.

To all whom it may concern:

Be it known thatl, JAMES R. COVE, a citizen of the United States,'residing in Arlington Heights, in the .county of Middlesex, in the State of Massachusetts, have invented certain new and useful Im rovements 'in urled Flaked Soap, of which the followingis a specification. a

The invention relates to apparatus for producing curled flaked soap.

Flaked soap is commonly sold at retail in cartons which are automatically filled, weighed and sealed. WVhen the cartons containing the flaked soap leave the packing and weighing machine they are substantially full. The handling of the cartons and the shaking to which they are subjected in transportation cause the soap flakes as heretofore made to be more or less broken up and reduced in size. Sometimes the soap flakes are broken up to such an extent that they pack together more closely than when the cartons aie filled. The result is that when a user opens a package she finds that the soap flakes do not fill the carton and she naturally concludes that the package is under weight and that she is not receiving a fair return for her money. Flaked soap being packed and weighed by automatic machinery, the filled cartons all weigh substantially the same and contain the same amount of soap when they leave the weighing machine. This fact is unknown to the ordinary purchaser, who judges the weight by the apparent quantity.

Theobject of the present invention is to eliminate, as far as practicable, the tendency of the soap flakes to settle in the cartons. The desideratum is to so form the soap flakes that when they are placed in cartons they will remain in substantially the condition in which they left the soap finishing or flaking machine, so that the cartons will reach the user in substantially the condition in which they leave the packing and weighing machine. To the accomplishment of this object, the soap flakes are curled or rolled as they leave the flaking machine. ,The invention contemplates the production of curled soap flakes whether or not the sheet of soap is cut previously to thecurlin or rolling operation, but it is considere desirable, for the best ,results, to cut the soap, as in the manner shown in my copending application,

Serial No. 597,711, filed: October 30, 1922, previous to curling-it. The invention is more fully described hereinafter and is particularly pointed out in the appended claims.

In the accompanying drawings illustrating the preferred form of the invention, Fig. 11s a plan (with parts broken away) of curled soap flakes; Fig. 2 is an end elevation, partly in section, of the apparatus shown in Fig. 1; Fig. 3 is a transverse section, on an enlarged scale, through the scraper by which the sheet of soap is removed from the finishing roll and by which e soap flakes are curled or rolled; Fig. 4 is a diagrammatic view of the portion of a sheet of soap cut transversely and longitudinally previous to its removal from the finishing roll;

Fig. 5 is an enlarged perspective View of one of the soap flakes before curling; and Fig. 6 is a perspective view of a curled flake.

The apparatus of the invention may be applied to any usual or preferred form of the improved apparatusfor producing the v soap machine having a finishing roll over which a sheet of soap is adapted to be fed. The discharge end of such a machine is shown in the drawings. The finishing roll 10 is mounted on the shaftll journaledin The a scraper 14 arranged transversely at the front end of the machine, with its upper or scraping edge 15 set in close proximity to the finishing roll. All these parts (with the exception of the upper end of the scraper) are of common and well known construction and need no further description.

It is assumed for clarity of description and illustration that the sheet of soap is cut before it is scraped from the finishing roll.

For this purpose I make use of the arrangement of cutters disclosed and claimed in my said application. The transverse cuts 15 in the sheet of soap are formed by a spiral cutter 16 arranged so as to rest on the traveling sheet of soap and be turned thereby. The spiral cutter 16 is mounted on a shaft 17 'ournaled in the hubs 18 of arms 19 pivota y mounted on the rod 20 which is supported from the brackets 21 secured to the :1 moving 1 soup so surf which 1122;; npprmiiproduce :1 xhfl'urem the form 0. am
